Description
Technical field
The present invention relates to a kind of particle classifying and press dry device.
Background technology
Particle classifying press dry device and includes the filtration grader and press dry filter, filters decomposition and press dry into powder for the powder that will be scattered in the different progression of mother liquor.The filtration grader that existing particle classifying press dry in the device is generally interior cross-flow filtration grader, its structure of tradition includes housing 1' and is arranged at the interior microporous pipe 2' of housing, as shown in Figure 1, when filtering classification, mother liquor flows in microporous pipe, and penetrating fluid (also claim classification liquid, have powder granule after the classification) passes the microporous pipe parietal layer and flows out from inside to outside, bulky grain circulates in microporous pipe, and penetrating fluid is at the microporous pipe exchange set and be drawn out to outside the equipment.
The particle classifying technology of cross-flow in this, microporous pipe is after obstruction or fouling, need by the microporous pipe of oppositely pressurizeing in the microporous pipe outside, carry out backwash, because the microporous pipe outside is the mother liquor chamber of large volume, make the housing of grader bear bigger backwashing pressure during backwash, and be subject to the restriction of machining accuracy and material property, the backwashing pressure that large-sized housing can bear is very limited, therefore, need carry out the strictness restriction to the size of backwashing pressure, prevent that backwashing pressure from making housing, and the appearance of the junction of the microporous pipe of enclosure interior is damaged, and the powder that causes filtering classification is polluted, on the other hand, strict limited just because of backwashing pressure, the backwash effect of the microporous pipe of this traditional interior cross-flow filtration grader is very poor.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming and defect that prior art exists, and a kind of reasonable in design be provided, backwash efficiently easily particle classifying press dry device.
For achieving the above object, technical scheme of the present invention is to include the mother liquor batch can, the filtering flow container and at least one-level filter classification and press dry group, described filtration classification press dry group and includes the filtration grader and press dry filter, described filtration grader is outer cross-flow filtration grader, should include housing by outer cross-flow filtration grader, and be arranged at least one porous body in the housing, described housing is provided with the mother liquor chamber, and the mother liquor import that is communicated with the mother liquor chamber and mother liquor outlet, described porous body is arranged in the mother liquor chamber, this porous body includes outer wall and the inner chamber of sealing, outer wall is provided with the classification micropore of aperture unanimity, and should and the inner chamber of porous body only be connected with the mother liquor chamber by the classification micropore, be connected with classification liquid passing away on the inner chamber of described porous body, this classification liquid passing away passes housing and draws outside housing, the described inlet that press dry filter is connected with classification liquid passing away, the described liquid outlet that press dry filter is connected with the filtering flow container, described mother liquor batch can is connected with the mother liquor import of outer cross-flow filtration grader, and each filters, and dish is connected to the backwash high pressure passage on the classification liquid passing away of the outer cross-flow filtration grader that classification press dry group.
By this setting, mother liquor is transported to the mother liquor import of filtering the outer cross-flow filtration grader that classification press dry group from the mother liquor batch can, particle in the mother liquor is penetrated in the porous body from outside to inside, finish outer cross-flow filtration classification, classification liquid after the classification is incorporated into and press dry in the filter, carrying out press filtration washs and press dry, this setting, the present invention utilizes above-mentioned structure setting, when backwash, the high pressure of introducing is linked on the classification liquid passing away, therefore, backwash high pressure only acts on the porous body inside, and porous body be generally metal material or nonmetal sintering forms, its anti-pressure ability is strong, therefore, can introduce higher relatively backwashing pressure, make backwash effect efficiently remarkable.
Further arrange is that described filtration classification press dry group and also includes classification batch can and classification liquid delivery pump between the inlet that is arranged at classification liquid passing away and press dry filter.
Further arrange is that described filtration classification press dry group and is provided with three groups, and these three groups are filtered the mother liquor outlet connection successively that classification press dry three outer cross-flow filtration graders in the group, and the mother liquor outlet that is positioned at the outer cross-flow filtration grader of last level is communicated with the mother liquor batch can.By this setting, realize the multistage classification of powder and press dry operation that diverse in function is used flexibly.
Further arranging is that described porous body is microporous pipe, micropore ball or micropore dish.
Further arranging is that described porous body is metal micro-holes body or nonmetal sintered microporous body.
Below in conjunction with specification drawings and specific embodiments the present invention is done further introduction.
